- Twink - a thin, mostly bodyhairless gay man
- Twunk - a muscly, mostly bodyhairless gay man
- Bear - a hairy, thicker gay man
- Otter - a thinner but still hairy gay man
- J/O - jerk off
- Frot - touching two penises together, usually while j/o with each other
- Top - the person who is topping is the person penetrating
- Bottom - same but is instead the person being penetrated
- Verse - likes being both top and bottom
- Side - I’m less familiar with this one but given the quotes and context I’m assuming this is not a top or a bottom or a verse, but instead is someone less interested in penetration and more interested in body contact and j/o together. *
I can give more of an answer. There is (or was) a birth control method called the sponge, or the today sponge. It is entered into the vagina and pushed up against the cervix, blocking the entrance, and it contains spermicide as well.
In s7e9 of Seinfeld, the sponge is discontinued, causing Elaine to panic (as it is her preferred method of birth control) and search across the city to find more sponges. When she does find and buys a case, she then realizes that even though she has more sponges, she may never be able to get more, and thus starts to debate on whether her current boyfriend is “sponge worthy”
